You're a mess, Jay. Yeah, can relate, though not personally. I had to go through hyperbaric treatment for a couple of months for a really nasty & persistent big-toe ulcer a couple of years ago, & the guy who was in the other tube most of the time had it even worse than I did, eventually losing the big toe on his right foot when it Just Would Not Heal, hyperbaric therapy or no. Me, I was lucky. They eventually got the ulcer healed & I went through surgery to straighten the foot; no problems with it at all since, thank heaven. Really glad the important parts of you remain with us!
BTW, for those of who you don't know about hyperbaric tubes, essentially they look a little like an iron lung (yes, serious), except with the head enclosed too. (You don't get claustrophobic, since the tubes are transparent except for the end panels.) They slide you in, then seal it up & pressurize the thing to roughly two atmospheres for about 2 hours, & you do that 5 days a week for about 2 months. It's an interesting experience, but the increased oxygenation significantly improves the healing.
